Claims

[Scope of utility model registration request]

A radar device that has the function of searching, detecting, and tracking a target and receives echoes from the target includes a transmitting and receiving antenna that emits high-frequency power pulses to the outside and receives reflected waves from the target, and the above-mentioned high-frequency power A transmitter section that generates pulses, a transmission/reception switching section that switches between transmission and reception, a mixer that converts the received waves inputted through the antenna and the transmission/reception switching section to an intermediate frequency, and a mixer that converts the received radio waves to an intermediate frequency. A local signal generation section that creates a local signal for conversion, a receiver section that amplifies the output signal from the mixer and converts it into a video signal, and a distance,
A signal processing unit that processes angle tracking, a scope that displays distance video, an automatic frequency control circuit that controls the above local signal, and an automatic frequency that introduces a part of the local signal and a part of the transmitted signal. a control mixer, a bite signal generator that generates a bite target to simulate the received echo when there is no received echo from the antenna, a distance pulse 2 part that determines the distance of the bite target, and a bite signal generator that generates a bite target to simulate the received echo when there is no received echo from the antenna; a byte local signal generation unit that creates a local signal, a loop coupler that extracts a part of the local signal and the transmitted signal, a byte/calibration injection status that is output when performing a byte or calibration injection,
The output of this status indicates that the device is equipped with a changeover switch for switching between the local signal and the automatic frequency control loop, and a servo drive circuit that controls the transmit signal of the transmitter section when the automatic frequency control loop is switched. Characteristic radar equipment.
